How would you solve the boring "damage rotation" of the healers?

Personally I did not like the healer design in WoW very much, especially the rule that you would have to stand around doing nothing for 5 seconds until your MP starts regenerating was a killjoy.
Regardless, here's another idea: Similarly to PvP, create designated kits for High-End content.
The problem of the 9? years of baggage this game has, limits future design choices to "more of the same" if you do not want to break anything. More of the same has been the answer for so long, it has become the expectation. It's a dead, uninnovative end from what I have seen in ShB and EW.

One alternative is to break things and fix them afterwards. The other is to create a new environment separate from the previous.
The first seems to be not what Square usually does, at least the fixing part. Just have a look at how T7S is barely manageable with today's toolkits. Not really broken but neglected is all the synced content that just gets easier (dps-wise) by every expansion's power swell.

A seperate toolkit for high-end content could be a solution. Maybe it could be stable per expansion as to keep balancing over the course of the years.

I'll be brutally honest; a separate toolkit for high-end PvE and casual PvE is a horrible idea, it only further segregates and separates the two playerbases. A new player that wants to get into raiding now has to throw out 90 levels worth of job knowledge because raiding uses a different skillset, while someone who does lots of raiding suddenly gets disoriented just from doing MSQ and roulettes. It's one thing for some content to offer unique skills, Eureka with Logos Actions and Bozja with Lost Actions come to mind, but they don't throw out the current job kit and only add to it.

PvP and PvE is separate because how you interact is fundamentally different. A boss following a script and at most using a random number to decide how it might do a mechanic is very, very different from a thinking opponent who can react dynamically, and as such their movesets need to be designed and balanced differently.
